Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Adding General Double Click Anywhere - Unity

Hey fellow HoloDevs!

I just wanted to share a way I am setting up a double click custom event in your scene without having to be over a certain object with a collider or UI component.

First, add the prefab from the HoloToolKit-Unity "InputManager". Under that you will notice a "GesturesInput.cs" script.

Next open that script up.

Go to the OnTappedEvent.

Just above it add:
public UnityEvent DoubleClickAction; private int clickCount = 0;

Next go into the method, at the end of it add:
clickCount++; if(clickCount == 1) { StartCoroutine(waitForDoubleClick()); }

Now we can create the waitForDoubleClick() method:

IEnumerator waitForDoubleClick() { yield return new WaitForSeconds(.5f); if(clickCount >= 2) { Debug.Log("[GESTURE INPUT] Double Clicked"); DoubleClickAction.Invoke(); }else { clickCount = 0; } clickCount = 0; }

I made my wait .5 seconds, but you can change that to make it longer or shorter. Now go back into Unity and setup your Unity event to invoke the call on another script on another object.

Have fun!
